Cisco 8200 router install mode IOS upgrade

[yum3372]

Hi guys,

It's the first time for me to commit upgrade on cisco router 8200. it's running by 17.6.6a. and I wanna change it to 17.12.4.

Rommon ver is 17.6(8.1r). seems like it's recommended version that Cisco guarantees. 

And the router is in install mode. is it totally same procedure as any other cisco switch when I upgrade the IOS? or any other guide line for router product?

Be aware that Cisco has released a re-build, 17.12.4a, last week (18 December 2024).  Making a re-build available is very time consuming (think:  Expenses) and will only happen if something is definitely (if not catastrophically) wrong with main build.

IOS upgrade command was totally same as other catalyst switch series.
